Former Facebook product manager Antonio Garcia Martinez begins his memoir with the following dedication: "To all my enemies: I could not have done it without you." A tech insider, Martinez sold a startup to Twitter and was then hired -- and later fired -- by Facebook. His new book "Chaos Monkeys" shatters some of the myths of startup culture and provides a window into the day-to-day workings of Silicon Valley, including the double-dealing and depravity he willingly participated in.
